Lumicyle XPG upgrade... worth it still? Lumi SYS4 Can it be trouted??

Has anyone sent their lamp back for the XPG upgrade? I have a SYS4 from a few years ago, thinking about the XPG upgrade but with crop of magicshines / gloworms X2 I'm wondering if my money would be better spent elsewhere.

Hi Trout, not sure if there is a link but I did speak to them about an upgrade service, If I remember correctly they would put their latest LED's (XPG) in my SYS4 for around £95.

They said it would need new LED's and driver etc, (included in the £95 cost). Does this sound reasonable? I'm not sure if this would give me a comparable lamp, with one of the current systems out at the mo.
